Disclaimer: AlertSCC is effective and efficient, but you should not rely on it exclusively. This system supplements, rather than replaces, other communication methods used by emergency responders, both in person and through the use of other media. Television, radio and County/city websites will continue to broadcast important announcements as well. AlertSCC communications are dependent upon external providers such as your wireless carrier or e-mail delivery service. County of Santa Clara government cannot guarantee that notifications will be received by the intended recipient. Service costs from your carrier are your responsibility.
